Koopa Guy

Koopa Guys are GreenShy Guys inside Red Koopa Shells. They appear in large colonies and can attack very quickly, as well as defend from the MarioBros. with their rock-hard shells. Their attacks are no joke; a 50-power Ram attack or a huge 140-power Charge Shot. Their other attacks are similar to those of regular Red Koopa Troopas and regular Shy Guys.

Bowser does not approve of Koopa Guys, as too many Red Koopas, the smarter of the Koopa species, sacrifice their lives to provide for these Guys. The cost is low, though; Koopa Guys pack immense power and Mario and Luigi have not defeated any... yet.
